The percentage of drug users who develop addiction can vary depending on several factors, including the type of drug, the frequency and duration of use, and individual factors such as genetics and mental health. However, according to the National Institute on Drug Abuse (NIDA), about 9 percent of people who use drugs will become addicted to them. This percentage varies depending on the drug, with some drugs having higher addiction rates than others. For example, opioids and methamphetamine have a higher addiction potential than drugs such as marijuana or cocaine. It’s important to seek professional help and support if you or someone you know is struggling with drug use or addiction, as early intervention and treatment can improve outcomes and reduce the risk of negative health consequences.
